Continuous-time 8th-order filter in a 28-SOIC
The Maxim Integrated MAX274BCWI+ is a continuous-time, 8th-order filter IC that can be configured as either a bandpass or lowpass filter. It integrates four 2nd-order filter sections in a single 28-SOIC package, allowing the designer to implement two 8th-order filters or four independent 2nd-order stages. The cutoff or center frequency is rated at 150 kHz, making it suitable for anti-aliasing, smoothing, or signal conditioning in the audio and low-frequency instrumentation range.
Package and handling for the storeroom
The MAX274BCWI+ ships in a tube (not tape-and-reel), so it is easy to store on a shelf without worrying about moisture-sensitive reel seals. The 28-SOIC wide-body package (0.295" body width, 7.50 mm) is a standard footprint for analog ICs and is straightforward to hand-solder or rework. Surface-mount only — no through-hole variant.
It is ROHS3 compliant.
